莒县地声台网与地声数据处理系统
THE GEOSOUND NETWORK OF JUXIAN AND ITS DATA PROCESSING SYSTEM
-
摘要: 对地声、极微震的研究是目前国内外一个探索性课题。我国在山东省莒县建立了一个标准地声台网。本文详细介绍和讨论了该台网及其观测系统、记录系统、监测能力、环境噪声等;介绍地声极微震高频信号的数据处理系统;讨论了该台网的定位方法及一些事件的定位结果,得到了郯庐断裂带中段四条断裂的不同的活动情况。Abstract: Now,the research on geosound and micro-microearthquakcs is a frontier subject in and outside China. A geosound network has been set up in Juxian,Shandong province. In this paper,we shall describe this network and its receiving and recording system,receiving capability,environmental noise and the digital-signal processing system for geosound and micro-microearthquake signals. We shall also discuss the method for locating the geosound source and the location results for some micro-microearthquake events. The results show different degrees of activity at the four faults of the middle segment of the Tanlu fault zone.
